[SOLVED] find -mtime not working

I am running 'find /backup/*-hourly.tar.bz2 -mtime +1', but get no results. My current date/time is 2020-03-26 12:19. If I list some of the older files in that directory I get:

-rw-r--r-- 1 root backup  498680817 2020-03-25 05:17 /backup/20200325051501-hourly.tar.bz2
-rw-r--r-- 1 root backup  495717033 2020-03-25 04:18 /backup/20200325041501-hourly.tar.bz2
-rw-r--r-- 1 root backup  503292281 2020-03-25 03:18 /backup/20200325031502-hourly.tar.bz2
-rw-r--r-- 1 root backup  503634015 2020-03-25 03:05 /backup/20200325030103-hourly.tar.bz2

I also tried 'find /backup -name \*-hourly.tar.bz2 -mtime +1'

Why is my 'find' not listing all of these files? What am I doing wrong?

Fractional parts are ignored, so files selected by "-mtime +1" would have to have a modification time at least 2 days ago, "2" being the smallest integer greater than "1". It's explained in the manpage, where the description for "-mtime" references the note under "-atime".

Ah, you are right. I did read the man page, but did not follow up on the note referencing -atime on rounding. Thanks.

here's the solution:

find /backup/*-hourly.tar.bz2 -mmin +1440 -exec rm -v {} \;

Or -mtime +0
